I went to the strip to test my mxz800-01. 500ft.Rkt,dynoport,boeysen reeds. *jetting was 20 pilot ,fuelskrew 3 turns out,380 main.380`s fields ways to rich,no power at topend. I wonder if anyone else has run with smaller mains??? I think 360`s maybe will be better. http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/sleeping.gif
